Description

Technical Field

[0001] This utility model belongs to the field of unmanned agricultural machinery, specifically relating to a safety protection device for unmanned agricultural machinery. Background Technology

[0002] In the field of agricultural production, the application of unmanned agricultural machinery has brought many positive impacts. It can operate autonomously in different agricultural scenarios, effectively reducing labor costs, improving the efficiency and precision of agricultural production, promoting the development of agricultural production towards intelligence and modernization, and providing strong support for the transformation and upgrading of the agricultural industry.

[0003] In the practical application of some existing unmanned agricultural machinery, there is a lack of safety protection devices that combine "sensing" and "control" to form an independent, highly reliable safety loop. When the sensing module detects an obstacle or an emergency command is issued from the cloud, it may not be able to bypass the main control system in time to directly trigger effective protective actions. This can easily lead to the agricultural machinery failing to promptly implement alarm functions, cut off power output, and activate mechanical braking, which may result in safety accidents such as collisions and loss of power control, causing damage to personnel, agricultural machinery and equipment, and the agricultural production environment, and seriously affecting the safety and stability of agricultural production. Therefore, there is a need for a safety protection device for unmanned agricultural machinery. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed safety protection device for unmanned agricultural machinery in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A safety protection device for unmanned agricultural machinery includes a vehicle body, an exhaust pipe fixed to the right side of the vehicle body, a safety protection component fixedly installed on the inner side of the vehicle body, an emergency anti-collision component slidably installed at the front end of the vehicle body, and a towing component fixedly installed at the rear end of the vehicle body.

[0007] The safety protection components include a control unit fixedly installed inside the vehicle body, an emergency button fixedly installed on the left side of the vehicle body and electrically connected to the left side of the control unit, an electromagnetic brake valve fixedly installed on the inner side of the vehicle body and electrically connected to the control unit, a first anti-collision radar fixedly installed on the lower front surface of the vehicle body and electrically connected to the control unit, and a second anti-collision radar fixedly installed on the lower rear surface of the vehicle body and electrically connected to the control unit.

[0008] As a further optimization of this utility model, the emergency collision avoidance component includes a spring-type pressure sensor fixedly mounted on the front surface of the vehicle body. The spring-type pressure sensor is electrically connected to the front end of the control unit via a wire, and a collision avoidance beam is fixedly mounted on the front end of the spring-type pressure sensor.

[0009] As a further optimization of this utility model, two connecting blocks are fixed on both the left and right sides of the anti-collision beam. A sliding groove is provided on the rear surface of each connecting block. Two threaded bolts fixed to the outside of the vehicle body pass through each sliding groove. The connecting block slides back and forth slightly between the outside of the vehicle body and the nut of the bolt.

[0010] As a further optimization of this utility model, the towing assembly includes a connecting pin fixedly disposed on the rear surface of the vehicle body, a crossbeam fixed on the upper side of the connecting pin, and a towing hook perpendicular to the horizontal plane fixed on the surface of the crossbeam.

[0011] As a further optimization of this utility model, swing arms are rotatably connected to both sides of the connecting pin, and each swing arm has a connecting hole for hinged connection with agricultural implements on the surface of the end away from the connecting pin.

[0012] As a further optimization of this utility model, the detection direction of the first anti-collision radar is towards the front of the vehicle body, and the detection direction of the second anti-collision radar is towards the rear of the vehicle body. Both of them are connected to the control unit through wires to form a signal transmission connection. The control unit is connected to the electromagnetic brake valve to form a braking control signal output connection.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, after receiving the signal, the control unit directly triggers the audible and visual alarm, cuts off the power output, and starts the mechanical brake through the hardware circuit. This mechanism enables unmanned agricultural machinery to bypass the main control system and respond quickly when facing safety risks, forming an independent and highly reliable safety loop, effectively avoiding safety accidents caused by system delays or malfunctions, and greatly improving the safety of people, machines, and the environment during agricultural machinery operation.

[0015] 2. In this utility model, the emergency button can be manually triggered to issue emergency commands, the anti-collision radar can detect obstacles in front and behind, and when the anti-collision beam is impacted, the electrical signal spring absorbs potential energy and generates an electrical signal that is transmitted to the control unit. The combination of multiple signal transmission methods realizes multi-dimensional monitoring and control of the safety status of agricultural machinery. Whether it is human emergency intervention, obstacle detection or physical collision, it can trigger safety protection actions in a timely manner, greatly improving the comprehensiveness and sensitivity of safety protection, ensuring the safety and reliability of unmanned agricultural machinery when operating in complex agricultural scenarios, and building a solid safety defense line for intelligent agricultural production.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example: Figure 1 , Figure 2 and Figure 4As shown, a safety protection device for unmanned agricultural machinery includes a vehicle body 1, which carries various components and serves as the main body of the unmanned agricultural machinery. The vehicle body 1 is existing technology and will not be described in detail below. An exhaust pipe 2 is fixed to the right side of the vehicle body 1. A safety protection component 3 is fixedly installed on the inner side of the vehicle body 1. The safety protection component 3 integrates control, detection, and braking components to achieve safety protection. The safety protection component 3 includes a control unit 301 fixedly installed inside the vehicle body 1. An emergency button 302 is electrically connected to the left side of the control unit 301 and is fixedly installed on the left side surface of the vehicle body 1. The emergency button 302 is used by the operator to press and send a stop signal. An electromagnetic brake valve 303 is fixedly installed on the inner side of the vehicle body 1 and electrically connected to the control unit 301. A first anti-collision radar 304 is fixedly installed on the lower front surface of the vehicle body 1 and electrically connected to the control unit 301. The first anti-collision radar 304 is used to detect obstacles in front of the vehicle body 1 and send a stop signal. A second anti-collision radar 305, electrically connected to the control unit 301, is fixedly installed on the lower rear surface of the vehicle body 1. The second anti-collision radar 305 is used to detect obstacles behind the vehicle body 1 and send a stop signal. The detection direction of the first anti-collision radar 304 is facing the front of the vehicle body 1, and the detection direction of the second anti-collision radar 305 is facing the rear of the vehicle body 1. Both are connected to the control unit 301 through wires to form a signal transmission connection. The control unit 301 and the electromagnetic brake valve 303 form a brake control signal output connection. After receiving the stop signal, the control unit 301 sends instructions to the electromagnetic brake valve 303 and the audible and visual alarm device. The electromagnetic brake valve 303 will open the high-pressure oil passage, allowing the high-pressure medium to quickly enter the brake cylinder in the unmanned agricultural machine, pushing the piston to press against the brake shoes. The shoes and brake drum discs rub violently, and at the same time, the return oil circuit is cut off to prevent pressure loss, instantly generating a strong braking force to realize the emergency braking of the unmanned agricultural machine.

[0024] like Figures 3 to 5As shown, an emergency anti-collision component 4 is slidably mounted on the front end of the vehicle body 1. The emergency anti-collision component 4 is used to trigger a stop signal when subjected to impact. The emergency anti-collision component 4 includes a spring-type pressure sensor 402 fixedly mounted on the front surface of the vehicle body 1. The spring-type pressure sensor 402 transmits a stop signal to the control unit 301 after being impacted by the anti-collision beam 401. The spring-type pressure sensor 402 is electrically connected to the front end of the control unit 301 via a wire. The anti-collision beam 401 is fixedly mounted on the front end of the spring-type pressure sensor 402. 401 is used to transmit force to spring-type pressure sensor 402 when subjected to impact. Two connecting blocks 403 are fixed on both the left and right sides of the anti-collision beam 401. The connecting blocks 403 are used to drive the anti-collision beam 401 to slide back and forth slightly to transmit the impact force to the spring-type pressure sensor 402. Each connecting block 403 has a sliding groove 405 on its rear end surface. Two bolts 404 threaded and fixed to the outside of the vehicle body 1 pass through each sliding groove 405. The connecting block 403 slides back and forth slightly between the outside of the vehicle body 1 and the nuts of the bolts 404.

[0025] like Figures 1 to 3 As shown, a towing assembly 5 is fixedly installed at the rear end of the vehicle body 1. The towing assembly 5 includes a connecting pin 501 fixedly installed on the rear surface of the vehicle body 1. The connecting pin 501 is used to connect the swing arm 504 to the vehicle body 1. A crossbeam 502 is fixed on the upper side of the connecting pin 501. A traction hook 503 perpendicular to the horizontal plane is fixed on the surface of the crossbeam 502. The traction hook 503 is used to attach the traction device of the agricultural implement, which facilitates quick connection and separation. Swing arms 504 are rotatably connected to both sides of the connecting pin 501. The traction hook 503 is used to connect with agricultural implements, etc. Each swing arm 504 has a connecting hole 505 for hinged to the agricultural implement on the surface of the end away from the connecting pin 501. The agricultural implement is hinged to the swing arm 504 through the connecting hole 505.

[0026] It should be noted that this type of unmanned agricultural machinery safety protection device, in addition to the operator issuing a prohibition command directly from the cloud during the operation of the unmanned agricultural machinery, also has three other ways to ensure safety protection with the unmanned agricultural machinery as the main body: First, the operator sends a stop signal by pressing the emergency button 302 set on the unmanned agricultural machinery; Second, the first anti-collision radar 304 and the second anti-collision radar 305 set at the front and rear of the vehicle body 1 send a stop signal when they detect obstacles around the unmanned agricultural machinery; Third, when an emergency occurs, after the anti-collision beam 401 is subjected to impact force, because the connecting block 403 can slide back and forth slightly on both sides of the vehicle body 1, the anti-collision beam 401 will transmit the impact force to the spring-type pressure sensor 402 when it moves back and forth with the connecting block 403. At this time, the spring in the pressure sensor will deform, and the sensor will transmit a stop signal to the control unit 301.

[0027] When the control unit 301 receives the stop signal, the internal hardware circuit activates the audible and visual alarm device, causing the front and rear lights of the unmanned agricultural machine to flash simultaneously and broadcast a warning. On the other hand, the control unit 301 sends a command to the electromagnetic brake valve 303 to cut off the power output of the unmanned agricultural machine and activate the mechanical brake, enabling the unmanned agricultural machine to stop moving quickly. The entire process bypasses the main control system and achieves safety protection for people, machines and the environment through an independent and reliable safety circuit.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
